我有一个Symfony项目，使用 composer 和React。我试图下载symfony/ux-react包与 composer 以下链接：https://symfony.com/bundles/ux-react/current/index.html但是，当我运行composer require symfony/ux-react时，我得到了以下错误：

- Downloading symfony/webpack-encore-pack (v1.0.2)

Cloning failed using an ssh key for authentication, enter your GitHub credentials to access private repos
When working with _public_ GitHub repositories only, head to https://github.com/settings/tokens/new?scopes=&description=Composer+on+lex-Blade-15-Mid-2019-Base+2023-01-27+1205 to retrieve a token.
This token will have read-only permission for public information only.
When you need to access _private_ GitHub repositories as well, go to https://github.com/settings/tokens/new?scopes=repo&description=Composer+on+lex-Blade-15-Mid-2019-Base+2023-01-27+1205
Note that such tokens have broad read/write permissions on your behalf, even if not needed by Composer.
Tokens will be stored in plain text in "/home/lex/.config/composer/auth.json" for future use by Composer.
For additional information, check https://getcomposer.org/doc/articles/authentication-for-private-packages.md#github-oauth
Token (hidden):

然后我创建一个令牌，复制粘贴到终端：

Token stored successfully.

有人知道解决这个问题的方法吗？看起来webpack-encore-pack已经贬值了。
